Installation
Pressurizing from an external pressure
source
!
WARNING! This pedestal must be pressurized only with
clean, dry air or nitrogen. A pressure reducing valve must
be fitted to the pressure line between the gas cylinder and
the outlet connection of the hose. The reducing valve must
be screwed into the gas cylinder outlet. The maximum
pressure on the outlet side of the reducing valve must not
exceed 15 bar (218 psi)).
Do not pressurize the pedestal beyond the maximum safe
working pressure indicated by the leading edge of the red
sector on the gauge. The pedestal is fitted with a pressure
relief valve as a safeguard against over-pressurization.
Do not attempt to adjust the pressure relief valve .
!
WARNING! A pressurized pedestal will rise rapidly when
safety catch is released. Do not release safety catch when
pedestal is pressurized and balancing load is not installed.
Always restrain the pedestal by hand pressure on the
steering ring when the safety catch is released.
To pressurize the pedestal from an external pressure source,
proceed as follows:
Attach the intended payload, ensuring that all items such as pan
bars, prompters, lenses etc., are fitted.
1.
Set the safety catch slide (14) to LOCK position (I) and fully
depress the moving column until the safety catch engages.
2.
Remove the Schrader valve cap (1) and connect the charging line
from the pressure source.
3.
Turn the steering ring until the pressure gauge is visible through the
window.
4.
Turn on the pressure supply and slowly increase the pedestal
pressure to the required pressure. Do not exceed the maximum
working pressure, indicated by the leading edge of the red sector
on the gauge (18).
5.
Disconnect the charging line, but do not refit the Schrader valve
cap at this stage.
